Bindings do not allow power-domain property in GCC clock controller and
documentation does not indicate that GCC is part of VDD_CX.

Maybe the bindings should be fixed? Maybe this was added as workaround?
Anyway looking at documentation I do not see such relation, except
downstream vdd_cx-supply (which is the same as in other SoCs and we do
not represent it in upstream).

Sure.
